I've applied online one evening and woke up to find an email with an invitation to attend an interview the morning after! After picking a day, I started doing my prep. On the day of the interview, I arrived about 45mins early but that was okay because I had a chance to meet some lovely people (it is absolutely crucial to talk to your peers of the day and make quick rapport because you will be observed from the moment you'll enter the building) who made me feel at ease. Altogether, there were 3 stages to the assessment: measurement/reach - all to do with health and safety. This was really easy! Afterwards, we got called one by one to do a role play activity where one of the assessors pretended to be a dissatisfied customer. After that came the group activity - also problem solving related. Unfortunately this is where my day came to an end. Advice though, I'd say there are no wrong or right answers to whatever problem you're given to solve - just try to remember to act as a team and not an individual. I haven't had a lot of experience in group interviews before so I think this is where I'd gone wrong. There were about 30+ of us and only about 8 people got through to the final stage so I didn't even feel that upset after all. Try to enjoy your day because it really isn't as daunting as you might think. The BA HR team are so friendly and positive, they'll immediately lift your mood and make you feel welcome. Some other tips I gained from today through either observing others or myself: - If you have piercings (other than ears) don't make the mistake of forgetting to take them out. - Let other people talk - Compliment eachother - Be positive, don't say anything that might upset other people or their views.
